FEEDBACK ZONE

"It's simply a brilliant ROM. Another masterpiece. Flashed 3.0 early in the morning. I came from another really good ROM but you topped it nevertheless. Don't know, how you do this. But that's not important as long as I can participate.",Louis235

"This ROM is just supernova and blazing fast, just 10.000 galaxys better than other ROMs, and I tried every ROM, keep it up bro with this amazing ROM "PandemicRecognized Contributor

"One word to describe this Rom = Legennnndary!!"XtremeSilencer

"Came back to ICS after switching between JB and GB for months. I must say that this rom is a beast in terms of performance. Ultimate HD 2.0.3 was good but 3.0.2 is simply amazing. I've been on this rom for 4 days now and there's still no decrease in performance. I dun know about others but i usually get 185+ free ram which is not bad for multitasking and gaming at all. And yeah HD games like RR3, NFS MW, Amazing Spidey, Sims Freeplay works amazingly well.
Can't expect more from a device with 2 years old Hardware.
Thanks for this Amazing Rom."

Benchmark, Battery Life and RAM

Battery Life and Performance? Impossible? Not anymore! Here are some nice screenshots

Q 1: After flashing Xperia Ultimate HD my battery life is not good. What can I do?
A: Please charge your battery to 100%, boot your device in ClockworkMod Recovery and go to Advanced ---> Wipe Battery Stats.
If this didn't help, please read this ---> [How to] Brilliant Battery Life 100% working!
Still Problems? Try to deactivate Auto-Sync, 3G Data when you don't use it, and the last thing you can do is, a kernel change // a new battery.

Q 2: I don't like onscreenbuttons // the "home, recent apps and back" key on my screen. How to disable it?
A: Go to Settings > Display > Softkeys, press "disable" and reboot. Now you can enjoy fullscreen

Quote:

Q 3: I'm using 2.0 on my phone, how to update to the next version?
A: Download the latest version of xperia ultimate HD and then please boot to clockworkmod recovery and go to advanced > wipe dalvik cache and than wipe cache partition. Now select install zip > choose zip from sdcard > Xperia Ultimate HD xxx.zip. Choose "Upgrade" in AROMA, and wait for the Installation to be finished. Now untick "reboot", go to advanced > fix permissions and reboot to system. The Bootup shold take 1 Minute, +/- related to the apps you have installed.

Q 4: My WiFi doesn't work. What can I do?
A: Flash WiFi Modules for your Kernel. If you are on stock kernel, reflash stock WiFi Modules. If you use Lupus, reflash the kernel and make sure you have a few mb left on the /system partition. If that, doesn't work, reflash the ROM and Check MD5 Sums.

Q 6: I have strange problems nobody ever had. lol. What can I do?
A: Using the right device? Reflash the ROM. If that doesn't work check the MD5 sums found at the download page with your MD5. Still no sucess? Try different Kernels..

Q 7: My favorite 3third party App doesn't work. Any Help?
A: Send me the Name and a Logcat of the Error and contact the developer of this app.

Quote:

Q 8: I don't have much free RAM. What can I do?
A: Remove Apps which you don't need, and which stay in RAM.. Timescape, Facebook, Whatsapp.. Than your Phone will run.. Like a BOSS.

Quote:

Q 9: I have a Bootloop. OMG what can I do ? Please help, I need my device in my job!
A: Well, first you should think about what to do if you got problems BEFORE messing up your device. Understood? Good.
If you followed the Instructions correctly you should be able to install it without any problems. If you did NOT, you may get a bootloop/problems, related to the mistake you did.
For restoring your device from bootloop, please restore your CWM Backup, reflash the ROM, OR Reflash Software using Flashtool/Sony Update Service.

Q 10: When You will release an Update?
A: I won't anwser this Question. Developer Rule: Dont ask for Estimated Time Arrival (ETA) = Don't ask for Updates. Help us to work by reporting bugs and problems to get better updates. Please do NOT ask. I will announce the Update when its ready.

Q 11: How do I make a proper bugreport?
A: With Information about:

Device

Kernel

ROM Version

Baseband

Did you make a Full Wipe?

When the bug occured?

Please Include also Screenshots and Logcats. It doesn't help me in ANY way, if you say: "my game fc". So don't exspect me to fix. Thanks

Quote:

Q 12: This ROM is very very slow and laggs what can I do?
A: Do a Full Wipe and follow the Instrcutions related to OP. Than you can enjoy this ROM as much as we do. Also, a different Kernel, whit more up-to-date sources is recomnend.

Q 15: Where is the Download Link? I can't find!
Some Browser or Anti Virus Programms hide the download image. To check, press on "show content". You should see an Yellow Download image. If you can't see, your browser hides this picture.

Quote:

Q 16: Can I install this ROM on locked bootloader?
Yes. You can without Problems.

Quote:

Q 17: I have a Camera FC. I can't take Pictures, what to do?
Reflash the ROM. Some Mods related to framework can cause FC's on this ROM. Please don't blame me =) (Ex: Not proper Walkman Port ^^^)

This is pretty outdated, but here are some good mods to choose from. Almost every mod for ICS is compatible with this ROM as well, incase you are unsure, backup your system partition in cwm and restore it, incase it doesn't work.

Kernel:WARNING: IF USE VENEGANCE KERNEL, DON'T REPORT PROBLEMS!
Use Lupus or advanced stock in Combination with this ROM
If AROMA is half on screen, use volume up and down to navigate. Its not a bug of my ROM.
Reserved....
Tips:
Your Phone charges in CWM (when connected to a charger)
logcats can be taken by "adb logcat" or with logcat app
Overclocking is dangerous & bad for battery life
